1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveCurrently, no practical biomarker is available for the diagnosis of acute ischemic stroke. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has being applied extensively to analyze large biomolecules such as proteins. The technique is likely to be of remarkable value as indicators of systemic processes such as atherosclerosis and stroke. The aim of this study is to identify potential protein biomarkers for ischemic stroke diagnosis utilizing MALDI-TOF MS.

methodsSerum samples obtained from acute ischemic stroke patients (n = 47) and controls (n = 34) were analyzed by MALDI-TOF MS. Stroke severity was assessed by the National Institutes of Health Stroke Scale (NIHSS), subtype by the Trial of Org 10172 in Acute Stroke Treatment (TOAST), functional outcome by the modified Rankin Scale (mRS) and infarct volume by the diffusion-weighted images. Risk factors and routine laboratory data of the stroke patients were registered prospectively.

resultsThe peaks of hemoglobin (Hb) alpha-chain and beta-chain were differentially expressed between stroke patients and controls (p < 0.0001). Hb ions were detected in the samples collected from 33 (70.2%) stroke patients and 5 (14.7%) controls. The sensitivity is 70.2% and the specificity is 85.3%. Among stroke patients, there is no significant correlation (p > 0.05) between Hb peaks and the NIHSS, TOAST, mRS, stroke risk factors, infarct volume, infarct location and laboratory data.

conclusionsSerum free Hb may serve as a novel potential biomarker for the diagnosis of acute ischemic stroke. The clinical value of this potential biomarker may be clarified by further studies quantifying serum free Hb levels.
